This yellow wildflower sucks strontium right out of contaminated soil

Phytoremediation
Rocky, mineral-heavy soils that look barren to most gardeners turn out to host plants that actively mine metals from the ground, and understanding which species do this is the first step toward using ordinary plants instead of heavy machinery to clean up polluted sites.
Scientists looked at a yellow-flowered plant called Alyssum murale growing on unusual rocky soil in Turkey and measured how much strontium it pulled out of the ground. The plant's roots and especially its shoots built up far more strontium than was in the soil around them, moving it efficiently from root to leaf. That makes this plant a strong candidate for phytoremediation, basically using plants as a natural cleanup crew for contaminated land.
Key Findings
Soil averaged 10.5 mg/kg strontium, while roots held 45.1 mg/kg and shoots held 141 mg/kg
Enrichment coefficients were 5.10 for roots and 16.4 for shoots, showing strong accumulation above soil levels
A translocation factor of 3.18 shows the plant efficiently moves strontium from roots up into shoots
chevron_right Technical Summary
A small yellow-flowered plant growing on mineral-rich soils in Turkey pulls strontium out of the ground and concentrates it in its shoots at levels far higher than the surrounding soil, suggesting it could help clean up strontium-contaminated land.

Phytoremediation Potential of Alyssum murale for Strontium in Serpentine Soils of Alacakaya Mining Area, Turkey.
In the Alacakaya region of Turkey, serpentine soils exhibit extensive surface coverage and contain high levels of Ni, Cr, and Co, and low levels of Sr. This study investigated the phytoremediation ...

Soil health is the capacity of soil to function as a living ecosystem, supporting complex interactions between microorganisms, soil fauna, and plant communities. For plant science, soil health is critical because these biological and chemical soil properties directly control nutrient availability,
